WOW, this is exciting, they look great and I was impressed with how easy it was to read, I even tried to put it right under a bright light and I could still see the screen well. The Sony Librie is a tremendous e-book. It uses E-Ink technology, which is so remarkably crisp that most people assume that the page on display is just a sticker (for demonstration.) In fact, unlike with a TFT display, you can view the Librie page from any angle. It comes with about 10mb of memory but you can bump up the size with the memory stick slot. 

This is like new textbooks for the future. Publishers like Random House, HarperCollins Publishers & Simon & Schuster and some others are supporting and supplying the service. You will be able to get the books through the Connect Store.  Interesting to see how this will play out in the education field and see what teachers and educators come out with some interesting ideas to interface and use these in the classroom. I think they will be out in the Srping or Summer this year - stay tuned.
